The main content of "Little Carp Jumping at the Dragon Gate": Grandma Carp told the little Carp a story about an ancestor yue longmen, saying that there is a paradise beyond the Dragon Gate, and only brave little Carp can jump over it. Hearing this, the little carp wanted to jump the dragon gate. So, under the leadership of the biggest herring, without telling grandma, I set out to find Longmen. They swam across rivers and rapids, overcame many difficulties and finally came to a magnificent reservoir. The dam here is high, the water is fast and the waves are high. They are all very happy, thinking that this is what grandma said about Longmen.

But no one can jump over the small carp and be washed down by the rapids again and again. Finally, herring came up with a way to make small carp jump one by one. When they arrived at the reservoir, they were stunned by the magnificent modernization. I saw the bright lights on the dam, factories, tall buildings and cars speeding. They asked the swallow what this place was. Swallow told them that this is Longmen Reservoir. The little carp really thought that he had jumped over the Longmen, so he happily asked the swallow to take a message back: Longmen is really good, let grandma come here, too.

He Yumen, the director at that time, said: "This play is all underwater, and there are many underwater shots." She drew it herself with flat glass, combined with various glues to design animation photography experiments and create new photography effects. For example, after finding out the position of carp's underwater activity and background activity, according to different positions, you can draw a little ripple on it in the place where the water movement is more intense without affecting carp's movement. After continuous exploration, we finally achieved the desired animation rendering effect.
